England Emancipated slavery in 1832 if i'm not mistaken. Also England recognized Brazil as a country even though Brazil was pro slavery. Another aspect to look at is the norths morale. If Lee had won on the 2nd day of gettysburg he would have had the man power to maybe take baltimore. If he had taken baltimore where the majority of it's citizens was pro south Lee could have made up for the losses he suffered at gettysburg.
